Hi!

   I've been sitting for a long time trying to figure out, if it's me who are
using far addressing in the wrong way, or there is a bug...
   As stressed several times in the manual I use the new keywords far and
chip on every global variable instead using -abcd and -b0 on the option-line.
This goes fine. After that I link without SmallData option using upstart
module c.o and library lcm.lib, lc.lib and amiga.lib. But suddenly the linker
drops out telling me, that there is a reference to an unmerged item??? But I
didn't want to merge it...The linker is not supposed to just creating simple
16bit addressing (Which is far too little when working with graphics). (I've
also tried to mess a bit with NOALVS, without succes.)
   After this depressing situation I jumped to the ultimate solution and
compiled every module with -b0 (took 2 hours). Still no problem except for a
40k larger program. And it links fine??? Should the new far and chip keyword
not work the same way as -b0? Should I use -ck?
   Now to the funny part. Before I ran the program I checked the available
memory, and after exiting there is missing 'bout 3k using the -b0 program???
All I've done is adding some chip data to the old program, which exits nicely??!
!!
Am I doing something wrong? or is it a bug?

P.S. I'm using Lattice C 5.10 from SAS institute.
